Definitions
- the object of the invention is a filter for electric pumps of windshield washers of motor vehicles.
- windshield washers of motor vehicles essentially comprise a reservoir of cleaning fluid disposed, for example, in the engine compartment, a suction electric pump for cleaning of the cleaning fluid, coupled to the reservoir of cleaning fluid, and conduits for connecting the Outlet of the electric pump with the jets that project the cleaning fluid on the windshield, the rear glass, etc.
- the electric pump it is common practice for the electric pump to have a tubular suction extension, which runs vertically through a wall of the cleaning liquid reservoir and is arranged inside it.
- the coupling of the electropump to the tank is carried out by means of fastening means coupled to a hole in the wall of the reservoir and which are traversed through the tubular extension of the suction pump; furthermore, in order to avoid the aspiration of solid bodies in suspension within the cleaning liquid, a filter element of the liquid aspirated by the electric pump is arranged.
- the assembly formed by said fastening means and filter element is designated as a filter.
- the filter for electric pumps of windshield washers of motor vehicles object of the invention comprises a body in which a first essentially cylindrical portion is distinguished, which coaxially links with a second portion also essentially cylindrical and of smaller diameter.
- the filter is characterized in that said first and second portions are axially traversed by a hole of constant section that forms a mouthpiece in the first portion and a bottom in the second portion, the second portion being provided with two suction openings, equal and diametrically arranged one with respect to the other, and of a tubular, inner and coaxial filtering mesh, the inner diameter of the filtering mesh being coincident with the diameter of the hole that axially crosses both first and second portions.
- the suction openings extend between the first portion and the bottom of the second portion.
- one end of the filter mesh is included in the first portion, while the other end is included in the bottom of the second portion.
- Another feature of the invention is that the link between the first and second portions configures a truncated conical portion.
- the outer edge of the mouth of the first portion is provided with a chamfering. It is also characteristic of the filter of the invention that the first portion is provided with an outer annular perimeter portion in cantilever.
- Fig. 1 is a side view of the filter according to the invention
- Fig. 2 is the view corresponding to section ll-ll of Fig. 1
- Fig. 3 is the view corresponding to the section lll-lll of Fig. 1.
- the filter 1 for electric pumps of windshield washer installations of motor vehicles which, as an exemplary embodiment, is shown, comprises a single-piece body 2 and a mutually coupled filter-tube mesh 3.
- the unipieza body 2 comprises a first essentially cylindrical portion 4 that axially links with a second portion 5 also essentially cylindrical and smaller in diameter than that of the first portion 4, said link forming a truncated conical portion 6.
- the end exterior of the first portion 4 is provided with an annular perimeter portion 7 in cantilever.
- the first cylindrical portion 4 and the perimeter portion 7 determine a means for securing the filter 1 to a hole made for this purpose in a reservoir of windshield washer fluid which, for the purpose of simplification, has not been represented.
- Fig. 2 it can be seen that the first portion 4 and the second portion 5 are axially traversed by a circular hole 8 which forms in the first cylindrical portion 4 an inlet opening 9 and in the second cylindrical portion 5 a bottom 10.
- mouth 9 is provided with a chamfering 11 and the axial hole 8 is sized to receive with tightness the tubular suction extension of an electric pump which, for the reasons indicated above, has not been represented, the mouth 9 being assigned to facilitate the entry into the axial hole 8 of said tubular suction extension during the coupling of the electric pump to the filter 1.
- the second cylindrical portion 5 is provided with two suction openings 12, equal to each other and arranged diametrically with respect to each other as can be seen in Figs. 1 and 3. Both suction openings 12 extend between the inner end of the first cylindrical portion 4 and the bottom 10 of the second cylindrical portion 5.
- the filtering tubular mesh 3 is arranged inside the second cylindrical portion 5 and coaxially therein, and consequently also coaxially disposed with respect to the first cylindrical portion 4, the inner diameter of the tubular mesh being filter 3 coinciding with the diameter of the hole 8 that crosses both portions 4 and 5.
- One end 13 of the filter tubular mesh 3 is embedded in the bottom 10 of the second cylindrical portion 5 and the other end 14 is embedded in the first cylindrical portion 4.
- the filter tubular mesh is obtained from polypropylene with a thread of 165 ⁇ m thickness and a light of 210 ⁇ m.
- the filter arrangement for electric pumps of windshield washer installations of motor vehicles object of the invention and which as an example of embodiment has been described, allows very easy priming at the origin of the windshield washer installation, without the need for repeatedly operate on the electric pump; furthermore, the described filter structure allows its production at a lower cost than the known filter embodiments.
